Do US politicians listen to science? Democrat-led congressional committees and leftwing think tanks cite research papers more than their rightwing counterparts, finds vast analysis by @dashunwang.bsky.social @alexanderfurnas.com www.nature.com/articles/d41... With comments from @ejfagan.com

First global pandemic treaty agreed — without the US The World Health Organization accord promotes sharing scientific data in exchange for more equitable distribution of drugs and vaccines.

“In this gloomy political environment, this gives us hope.” For the first time, nations agreed on how to deal with pandemics - amid COVID fatigue and without the US. One researcher even says that the US exit galvanised everyone else www.nature.com/articles/d41... @childsmichelle.bsky.social

How marathons change runners’ brains: scans point to surprise energy source After the gruelling races, levels of the nerve-cell insulator myelin were lower, suggesting the brain uses the fatty substance as fuel.

Two parts of my life collided this week when I wrote about how marathons affect the brain for @nature.com. I have run 14 marathons so glad to hear I've flexed my myelin elasticity! www.nature.com/articles/d41...

Two strands of my life collided this week when I covered marathons for @nature.com. I have run 14 marathons & happy to hear I've been flexing my myelin elasticity - with possible benefits! www.nature.com/articles/d41...
